STEP STRUCTURE.

SPECIFICATION fo; .r ing part of Letters Patent No. 697,434, dated April15, 1902.

Application filed July 31, 1901.

To all whom it may concern:

Be it known that I, HENRY W. BEARDSLEY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Step Structures; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in theart to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My present invention relates to improvements in steps; and it has forits object the production of a cement step structure capable of beingrapidly built without the exercise of special skill and which possessesgreat strength and rigidity and durability- The nature of the inventionwill be readily comprehended, reference being had to the followingdetailed description and to the accompanying drawings, in which- Figure1 is a perspective view,partly broken away, of a step structureembodying my invention. Fig. 2 is a longitudinal sectional View of amodification.

Referring first to Fig. 1, A A denote wooden strings having steppedupper edges (1, to which issecured by means of nails, staples, orscrews 1) b a step-base O, which may be what is known as expanded metalor wire-netting or their equivalent. D designates the treads, which areformed from cement or the like applied in a plastic condition and whichare anchored to the base by being forced through and beyond the openingsin said base. The base,

which may be continuous or in sections, extends transversely from stringto string and Serial No. 70,375. (No model.)

may be supported intermediately by another string or strings.

In Fig. 2 is shown a construction employing inclined wooden or othersleepers E, which support strings'F, formed by bent band-iron or thelike, the metallic strings being fastened to the sleepers by suitablesecuring devices, such as the nails, staples, screws, or bolts g g. Themetallic springs support the step-base C, the latter being secured,preferably, by the devices g, and said base serves as theanchoring-support for the cement treads D, as in the constructionillustrated in Fig. 1.

The upper surface of the cement tread portion may have any desireddesign or config uration, as the material of which it is composed isapplied in a plastic state. When set, the structure possesses lightnesscoupled with great strength and rigidity and durability. The steps may,as above stated, be rapidly constructed without the exercise of spe cialskill.

I claim as my inventionl. A step structure comprised of'strings havingstepped upper edges, a perforate tread and riser body secured to thestepped edge of the strings, and cement treads and risers supported byand anchored to the said body.

2. A step structure comprised of sleepers, metallic stepped stringssecured to the sleepers, a perforate tread and riser body secured to thestrings, and cement treads and risers supported by and anchored to thesaid body.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY W. BEARDSLEY.
